Shade and camera module having same

Abstract

A shade for a camera module is disclosed. The shade includes an optical aperture; a deformed portion extending outward from a wall of the optical aperture; and a fixed portion extending outward from the deformed portion. The deformed portion includes a body and a plurality of notches communicating with the optical aperture, and the notches pass through an upper surface and a lower surface of the shade.

What is claimed is: 
     
       1. A camera module including:
 a lens barrel having a first barrel wall forming an optical aperture, a second barrel wall extending perpendicularly from the first barrel wall, and an accommodation space formed by the first barrel wall and the second barrel wall; 
 a lens group installed inside the lens barrel and connected to the lens barrel, the lens group including an optical axis, and including: 
 a first shade having, in an order from an object side to an image side: 
 a first optical aperture; 
 a deformed part extending outwardly from a boundary wall of the first optical aperture, the first deformed part including a first body and a plurality of first notches communicated with the first optical aperture and passing through an upper and a lower surfaces of the first shade; 
 a first fixed portion extending outwardly from and non-coplanar with the first deformed part; 
 a second shade having: 
 a second optical aperture; 
 a second deformed part extending from a boundary wall of the second optical aperture, the second deformed part including a second body and a plurality of second notches communicated with the second optical aperture and passing through an upper and a lower surfaces of the second shade; 
 a second fixed portion extended outwardly from and non-coplanar with the second deformed part; 
 a second lens including: 
 a second optical imaging portion; 
 a second peripheral portion arranged around the optical imaging portion; 
 wherein 
 a projection of the first notch along the optical axis is located on the second body; 
 a projection of the second notch along the optical axis is located on the first body. 
 
     
     
       2. The camera module as described in  claim 1 , wherein the first barrel wall and the first shade, the second shade, and the second lens cooperatively form a shading structure. 
     
     
       3. The camera module as described in  claim 1  further including a first lens arranged between the first barrel wall and the first shade, wherein the first lens includes a first optical imaging portion and a first peripheral portion arranged around the first optical imaging portion, and the first peripheral portion of the first lens, the first shade, the second shade, the second peripheral portion of the second lens cooperatively form a shading structure. 
     
     
       4. The camera module as described in  claim 2 , wherein the second peripheral portion of the second lens is provided with a second lug attached to the second body and raising toward the first barrel wall. 
     
     
       5. The camera module as described in  claim 3 , wherein the first peripheral portion of the first lens is provided with a first lug attached to the first body and raising toward the second lens. 
     
     
       6. The camera module as described in  claim 1 , wherein the first notch have a third cutting surface, a fourth cutting surface separated opposite to the third cutting surface and a first connecting surface connecting the third cutting surface and the fourth cutting surface; a second angle θ 2  is formed between the third cutting surface and the fourth cutting surface, and the second angle meets the condition 0°≤θ 2 <180°. 
     
     
       7. The camera module as described in  claim 6 , wherein the second notches have a fifth cutting surface, a sixth cutting surface separated opposite to the fifth cutting surface and a second connecting surface connecting the fifth cutting surface and the sixth cutting surface; a third angle θ 3  is formed between the fifth cutting surface and the sixth cutting surface, and the third angle meets the condition 0°≤θ 3 <180°. 
     
     
       8. The camera module as described in  claim 1 , wherein the lens group comprises further at least a third lens located under the second lens; and the second lens and the adjacent third lens form a shading structure.
